Understanding Sonic drilling
What is sonic drilling? Sonic drilling is a technique that significantly reduces friction on the drill string and drill bit by using energy resonance to affect the soil structure where it contacts the drill string. This combination makes penetrating for a large range of soils much easier. Sonic drilling is most often used when the drilling is difficult and the integrity of the core sample is ...

Water penetration problems
Water penetration problems effect one out of every five acres in California (about 20 percent of the farm land) and it’s estimated that this costs growers $20 to $1,200 per acre. This problem is definitely worth taking a close look at since its quiet common in the central San Joaquin Valley. A more appropriate term to describe water entering the soil at the surface is infiltration. ...
